To all whom it may concern.'

Be it known that l, Vieron H. JENNINos, a citizen of the United States, residing at Viorcester, in the county of Worcester,

State of lllassachusetts, have invented a certain new and useful Improvement in Tubular llfoven Fabric with Widening, of

`which the 'following is a specification, ret'n erenoe being had therein to the acconipany .ing drawings.

nous with the first and of equal width therewith as produced in the loon; and woven -with a longitudinal told vor plait in the forni of a transverse return bend which enables such second section to be enlarged' by expanding or stretching it so as to straighten out theniaterial included in the fold or plait;Y

A web or fabric woven in conformity' with the invention, and a convenient fabu ric-structure for the same, are illustrated in the drawings, in which latter- Figurel is an elevation at a length of` the said. web or fabric. Fig.. 2 is a top,j view of the upper end of such length. Fig. 3 isa top view thereof showing the said end partly expanded. Fig. 4.1 is a diagrarn illustrating the fabriostrueture or the in.-`I termediate sections of the web or fabric. Fig. 5 is a diagram illust 'ating the fabricstructure of the sections which are formed With the integral Widenino'.

The web or fabric shown and described herein is woven in a flattened state.

.Having reference to the drawingsthe web or fabric shown comprises a section l of a given diameter, which section is or niay be of ordinary tubular weave, and a section 2 of tubnlar'weave having the integral widening portion 3 in the' form of a transverse return bend. The said widening portion comprises two additional plies of fabric woven intermediate the main portions ot the tube, and which are so conjoined transversely with the adjoining portions of section 2, and with each other, that they7 forni a .longitudinal fold or plait in such section. Thus, whereas in section l as herein illustrated there are two plies constitutingthe opposite side-portions of the fiattened tube, there are in section 2 four superimposed plies in a cross-section passing transversely throughthe longitudinai fold or plait.

A convenient fabriostructure is indicated in Figs. Il and. 5. Section l is woven in the usual Way of weaving tubular or hosepipe webstructure in fiat form. Fig. d will serve to illustrate the fabricstructure of thesaine. Thus, starting at the left hand' weft extends from the' right hand side `through a 'shed' in the warp-threads of the upper ply to the left hand side at a2. The

,third pick extends froml left to right through a second shed in the warp-threads ofV the lower ply. The fourth pick extends from right to left through a second shed in the warp-,threads of the upper ply toI the point 0,3. The picks and sheds are repeated in the order given. Figf will serve to illustrate the fabric-structure for the see-- tion 2. Thus, starting at the `left/hand side, the first pick otI weft extends 'through a shed in the warp-threads of the bottom ply of section Q to the right hand side at b. The second pick of Weit extends from `the right hand side through a shed in the right hand portion otl the warp-threads of the top ply of section 2 to an intermediate point at b2, and continues through a shed in the lower ply of the plait to the point 3.' -The third piek ot' wett extends from left to right through a shed in the warpthreads of the upper ply of the plait to a point at 7;? immediately alongside point i12. The fourth pick of weft extends from point if' through a shed in the left hand portion of the warp-threads of the top ply of section 2 to the lett hand side at b5. The fifth pick of wett extends to the right handside through'la second shed vin the warp-threads ol'vtheibottom ply. The sixth pick extends from the righthand side through a second shed in the right hand portion of, thev warp- Athreads of the top ply of section '2 to the point b2, and in the lower ply of the plait, to the point b3. The seventh pick extends from left to right through a second shed .in the warptlu'eads of the'upper ply of the plait to the point bt. The eighth pick extends from the point b4 to the left through a second shed' in the left hand portion of the warp-threads of the top ply to the point be. rlhe picks and shedding are repeated in the order given. The sections l and 2 are Woven in an alternating succession so as to lproduce a web of continuous tubular structure in which such sections are repeated a number of times. The warp-threads used in weaving the plait 3 are floated from one section 2 to the next, as indicated by dotted lines in Fig. l. The completed web is cut vup into lengths, each comprising a section 1 and a sectionQ, land the floated warpthreads are cut away. The location of the lait may vary transversely of the web or abrio, and may be Woven either inside or outside the tube. After the web has been cut across through thesection 2, as in sevl ering the continuous web into lengths, the

or other fastenings applied to the plait willA iserve to hold. the section 2 in its expanded and flared form, as in the application previously mentioned herein.

A widening produced in the manner herein explained has the special advantage that the fabric of the tube has, or may have, everywhere the same number of warpthreads and weft-threads to the square inch. In such case no difference in character or closeness of texture is apparent in section 2 at or adjacent the widening.

A special characteristic of the widening forming a feature of my invention is the fact that it is open at its ends, thereby facilitating the operation of sliding one portion of a pla-it or fold over upon another in adjusting the widening to the required dimensions. This also facilitates giving the required fiared or tapering form to the expanded part of the .sheath or the like in which the fabric is embodied.

l/Vhat is claimed is A seamless continuously-tubular fabric having a section of its length woven as a tube ot' a given diameter, and an adjoining section of equal width with the lirst as produced in the loom woven with an integral widening in the form of a longitudinal told or plait open at its opposite ends and forming an-open-ended transverse return bend which enables such second section to be given the form of'a flared widening with the material included in the fold or plait in a more or less straightened out condition, with the 'extent of remaining overlap varied in -the length of the widening.
